I have problem in test case 3 and 7 . Can anyone solve it i put my code in comments

def balanced(expression):
#your code goes here
list=[]
for i in expression :
if i=="(":
list.insert(0,i)
elif i==")":
list.pop(0)
if list==[] :
return True
else:
return False

print(balanced(input()))

Answer 1

What happens if the input is like this:

( ) ) (.

Does your code say true or false. Mine says false.

My code has a check that the number of ) is never larger as the number of (. If it happens i return false.

Answer 2

It return false

Answer 3
